odorizing Attachments for Gas-Heaters, of

which` the following is a specification, the

principle of the invention being herein ex-l.

plained and the best mode in which we have contemplated applying that principle, so as to distinguish it from other inventions.

The subject matter of this application is a device designed to be attached to gas heaters such as are largely employed in heating apartments, store-rooms and the like, and has as its object the purification and deodorizing of the gases of combustion escaping from such heaters whereby such gases may 29 be discharged directly into the apartment or room without ill eect. Such device involves the use of a suitable liquid for thus removing the undesirable products to which reference has been made, but the characterV of this liquid, other than that it will be ordinarily water or a solution largely composed of water, is not of present interest, the specific subject matter of the application being the apparatus itself, whereby such 3o purifying liquid is effectively and economically utilized for the purpose aforesaid.

Said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claim.

The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the 40 principle of the invention may be used.

In said annexed drawings: Figure 1 is a` perspective view of a gas heater of familiar type with one form of our improved deodorizing attachment connected therewith; Fig. 2 is a view, likewise in perspective, of such attachment by itself with the cover removed therefrom; and Fig. 3 is a longitudinal central vertical cross-section of the attachment with the cover in place.

It has been indicated that the heater illustrated in Fig. 1 is merely typical, since, as will be apparent from the following description, our attachment is designed for use with all the various forms of gas heaters, whether of the sort illustrated, or that which is entirely inclosed, or that in which an open asbestos grate is utilized. As in the typical structure A here illustrated, all these heaters are characterized by the provision of an external fine-connection a in its upper portion,

with which, in the ordinary mode of employing such heaters, a flue leading to a chimney or. the 'like requires invariably to be connected in order to conduct away the gases of combustion arising from the,burner in the heater. Our attachment is designed to be connected directly with such flue connection and will now be considered in detail.

This attachmentv comprises essentially a receptacle B that, in the form illustrated, is in effect an open rectangular box. Across the top of such box and intermediate between its ends there is secured a sheet b provided with a central opening b', and across the spaces between such sheet and the respective ends of the box is secured wire'mesh b2, Fig. 2. When in use, as shown in Fig. 1, the box is designed to be closed by a removable cover 3, such cover being provided with a gas inlet opening 'b4 disposed to register with the opening b in sheet Z) and surrounded by a sleeve b5 for external flue connection. Cover b3 is additionally provided with gas outlet openings be spaced from such central inlet opening b4 so as to lie over the strips of wire mesh b2. a flue a is connected to lead the gases downwardly from the flue connection a of the heater to the gas inlet opening b4 in the cover of the receptacle B, the latter being first filled preferably to a level such as is shown in Fig. 3, with a purifying liquid of the character previously referred to and not requiring more specific description in this connection for reasons already adduced. When the heater is in operation accordingly the gases from the burner, flowing downwardly through iiue a and into the receptacle B, impinge directly upon the body of liquid therein contained. By reason of the fact that the outlet openings from the receptacle are removed a considerable distance from the inlet opening, the gases are.forced to travel for an equivalent distance in close contact with the surface of such liquid, permitting the latter to exercise to the full its purifying effect and yet not materially retarding the flow of the gases, which would be objectionable, as it might interfere with the proper operation of the burner in the When assembled and in use stove or heater. lVhen the gases then tinally escape through outlet openings b they may freely mingle with the air in the apartment or chamber in which the heater is located without harmful or disagreeable effect.

le are aware that there are heaters constructed to utilize liquid to purify the gases arising from the combustion of the fuel in such heaters and we do not here claim broadly the principle of purification involved but simply the apparatus whereby such purification may be had in connection with any of the numerous forms of heater' already in use and not be limited to one of construction specifically designed for this particular purpose. Of the numerous advantages arising from this disposition of the of combustion no more than passing mention need here be made, it being well known that a large proportion Ofthe heat value of the fuel ordinarily goes up the chimney where a heater is connected therewith. Moreover the products arising from the burning of gas in heaters have a particularly harmful effect on chimneys by destroying the mortar between the bricks. All these diiliculties, as also the inconvenience and expense of tlues or pipe from heater to chimney, are avoided by apparat-us such as herein set forth.

Other modes of applying the principle of vided tlie means stated by the following claim or the equivalent of such stated means he employed.

le therefore particularly point out and distinctly claim as our invention:-

As an article of manufacture, a deodorw ing attachment for gas stoves comprising an open rectangular box adapted to contain a liquid, a sheet with a central opening cured across the top of said box intermediate between the latter`s ends, wire mesh Isecured across the top of said box between such sheet and ends, and a removable cover for said box, said cover heilig provided with a gas inlet opening` disposed to register with the opening in said sheet and surrounded by a sleeve for external tine connection and with gas outlet openings near its ends disposed to lie over such wire mesh.
